Dear Pepe,

I am pleased to offer you full-time employment with Radius Health, Inc. (“Radius” or the “Company”) as the Chief Financial Officer (“CFO”) of Radius reporting to Bob Ward, Chief Executive Officer of Radius. Your position will be based out of our Waltham corporate offices with a start date of May 15, 2017.

In the course of your employment with Radius, you will be subject to and required to comply with all Company policies, and applicable laws and regulations. The Company requires that, as a full-time employee, you devote your full business time, attention, skill, and efforts to the tasks and duties of your position with the Company. The term "Agreement" as used below shall mean this letter agreement.

The starting salary for this position is $17,083.33 on a semi-monthly basis, which annualized is $410,000.00 (less applicable taxes and withholdings).

This Agreement is contingent upon, and will become effective only upon, (i) your successful completion of a drug screening test and prior to your first day of employment; (ii) satisfactory results of a comprehensive background check (including, but not limited to, social security number, previous employment, conviction record, and education); (iii) proof of your eligibility to work for Radius in the United States; (iv) your commencing employment with the Company on May 15, 2017; and (v) ratification of this Agreement by the Company’s Board of Directors (the “Board”).

Bonus Eligibility

Commencing with the calendar year 2017, you will be eligible to participate in the Radius discretionary Bonus plan. Under this plan, your annual bonus incentive target will be 40% of your actual base earnings for the bonus plan year, and subject to Board approval, would be payable annually, generally in March of the plan year following the year to which the bonus pertains. Your actual incentive award will be based on your individual performance and the overall performance of Radius. Your bonus will be pro-rated during the first year of employment. The criteria and amount of the bonus will be determined on an annual basis, in Radius’ sole discretion.  You must be employed as of the pay-out date of any bonus in order to earn and be eligible to receive it.

Sign-On Bonus

You will be eligible to receive a Sign-On Bonus in the gross amount of $40,000.00 (less applicable taxes and withholdings).

As an inducement to your employment with the Company, and subject to receipt of necessary Board approvals following the date of the commencement of your employment with the Company, Radius will grant to you 125,000 non-statutory stock options (the “Options”) for the purchase of common stock of Radius, at a price equal to the closing price value of Radius’ stock on the date the Options are approved. The Options will vest as to 25% of the underlying shares on the first anniversary of the grant date and in equal monthly installments over the following thirty-six (36) months. The Options are intended to constitute an “employment inducement grant” under NASDAQ Listing Rule 5635(c)(4), and consequently are intended to be exempt from the NASDAQ rules regarding shareholder approval of stock option and stock purchase plans. The Options shall be subject to all terms, vesting schedules, limitations, restrictions and termination provisions set forth in a separate stock option agreement, outside of the Company’s 2011 Equity Incentive Plan, that shall be executed by you and Radius to evidence the grant of the Options.

Benefits

PERSONAL AND CONFIDENTIAL

Re: Separation Agreement and General Release of Claims

Dear Nick:

As we have discussed, this letter (the “ Separation Agreement ”) confirms your separation from employment with Radius Health, Inc. (the “ Company ”) effective as of May 17, 2017 (the “ Separation Date ”).  We thank you for your contributions to the Company.  We also wish to propose entering into a six-month consulting relationship commencing on the Separation Date, the terms of which are set forth in the accompanying Consulting Agreement.  

Accrued Rights

In connection with the ending of your employment, the Company shall pay or provide you with all of the “ Accrued Rights ” detailed in your Executive Severance Agreement dated July 1, 2015 (the “ Severance Agreement ”), including:

Stock Options

Under the Radius Health, Inc. 2011 Equity Incentive Plan (as Amended and Restated) (the “ Equity Plan ”) or any predecessor plan, if you enter into the Consulting Agreement effective on the Separation Date, the options that you hold to purchase shares of the Company’s common stock will continue to vest during your consulting relationship with the Company.  

You acknowledge that the following summarizes all vested options that have not been exercised as of the date of this letter and that shall remain exercisable by you as of the anticipated end date of your consulting relationship with the Company—November 17, 2017:

*Please note that, notwithstanding your continued vesting pursuant to your consulting relationship with the Company, under applicable tax rules, outstanding Incentive Options must be exercised by 08-17-2017 (i.e., three months after the Separation Date) to retain ISO status and receive preferential tax treatment.  ISO Shares that remain outstanding and exercisable after 08-17-2017 will necessarily convert to Non-Qualified Stock Options.

All of your options that are not vested as of the final day of your consulting relationship with the Company (whether such date is November 17, 2017 or an earlier date pursuant to Section 3 of the Consulting Agreement) shall lapse on that date and will not be exercisable.

The exercise of any vested stock options shall be subject to the terms of the Equity Plan, including, without limitation, the time limits on exercise, and nothing in this Separation Agreement is intended to modify in any respect the terms of the Equity Plan.  This summary is set forth solely to confirm certain information concerning your stock options.  

2

Severance

Further, because the ending of your employment constitutes a “ Qualifying Termination ” as defined in Sections 1(i) and 2(a) of the Severance Agreement, the Company shall provide you with the following additional severance benefits provided that you execute, do not revoke, and comply with this Separation Agreement and the General Release of Claims in favor of the Company attached hereto as Exhibit A within thirty (30) days of the Separation Date.  Exhibit A attached hereto is the “ Release ” defined in Section 2(d) of the Severance Agreement.

3

T he Company shall make deductions, withholdings and tax reports with respect to the payments and benefits detailed herein that it reasonably determines to be required.  The payments detailed in this Separation Agreement shall be in amounts net of any such d eductions or withholdings, and nothing in this Separation Agreement shall be construed to require the Company to make any payments to compensate you for any adverse tax effect associated with any payments or benefits or for any deduction or withholding fro m any payment or benefit.  You acknowledge that you are not entitled to any severance benefits, equity rights or other compensation except as expressly set forth in this Separation Agreement.  

Continuing Obligations

Finally, as a reminder, if you breach any of your obligations under the Confidentiality and Non-Competition Agreement between you and the Company dated December 15, 2015 (the “Confidentiality and Non-Compete Agreement”) or the Release, in addition to any other legal or equitable remedies it may have for such breach, the Company shall have the right to terminate its payments to you or for your benefit described herein.  The termination of such payments or benefits in the event of your breach will not affect your continuing obligations under the Confidentiality and Non-Compete Agreement or the Release.  

[REMAINDER OF PAGE INTENTIONALLY BLANK]

4

Please sign and return this Separation Agreement along with the Release within the timeframe set forth in Section 1 o f the Release. This Separation Agreement may be executed in separate counterparts.  When both counterparts are signed, they shall be treated together as one and the same document.  This Separation Agreement shall be interpreted and enforced under the laws of the Commonw ealth of Massachusetts, without regard to conflict of law principles.

Sincerely,

/s/ Deborah Kauffman
